BOSTON (AP)  More details about the case against the estranged husband of former Massachusetts Senate President Stan Rosenberg could emerge when Bryon Hefner makes his first court appearance.

Hefner is scheduled to be arraigned Tuesday in Suffolk Superior Court on charges of sexual assault, distributing nude photos without consent and criminal lewdness. He was indicted by a grand jury last month.

A report in The Boston Globe that several men had accused Hefner of misconduct led Rosenberg to step down as Senate leader in December. The Amherst Democrat, still a member of the Senate, has since separated from his husband.
